The 16HBE140 cell line is derived from human bronchial epithelial cells, which are essential for studying the respiratory epithelium. These cells retain several key characteristics of primary bronchial epithelial cells, including the ability to form tight junctions, express characteristic markers, and exhibit typical epithelial morphology. They are widely used in research focusing on respiratory diseases, drug transport, and toxicology studies, providing a reliable in vitro model to understand bronchial epithelial cell behavior under various conditions.
One of the significant applications of 16HBE140 cells is in the investigation of cystic fibrosis (CF), a genetic disorder affecting the respiratory system. These cells express the cystic fibrosis transmembrane conductance regulator (CFTR) protein, making them a valuable tool for studying CF pathophysiology and for screening potential therapeutic agents. Additionally, 16HBE140 cells are utilized in airway inflammation research, given their response to pro-inflammatory cytokines and pollutants, aiding in the understanding of chronic respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD).

Viruses: Transformant: Simian virus 40 (SV40)
- cultureMedium: EMEM (MEM Eagle), w: 2 mM L-Glutamine, w: 2.2 g/L NaHCO3, w: EBSS (Cytion article number 820100a)
- supplements: Supplement the medium with 10% Horse Serum and 1% NEAA
- dissociationReagent: Accutase
- subculturing: Remove the old medium from the adherent cells and wash them with PBS that lacks calcium and magnesium. For T25 flasks, use 3-5 ml of PBS, and for T75 flasks, use 5-10 ml. Then, cover the cells completely with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks. Let the cells incubate at room temperature for 8-10 minutes to detach them. After incubation, gently mix the cells with 10 ml of medium to resuspend them, then centrifuge at 300xg for 3 minutes. Discard the supernatant, resuspend the cells in fresh medium, and transfer them into new flasks that already contain fresh medium.
- freezeMedium: As a cryopreservation medium, use complete growth medium (including FBS) + 10% DMSO for adequate post-thaw viability, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress.
